To all whom it may concern:

Be it known that we, THEODORE YWEIN- SHANK and SIDNEY E. FnNsrnnMAKER, citizens of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Sectional Adjustable Ventilator-Casing, of which the following is a specification, reference being had to the accompanying drawings and to the letters and figures of reference marked thereon.

This invention relates to the ventilation of rooms or apartments of buildings and has reference more particularly to the control of the admission of fresh air and also to the heating or re-heating of the air for ventilating purposes, more particularly when the heating of the room or apartment is accomplished by means of radiators heated by steam or hot Water.

An object of the invention is to provide improved construction in ventilator base boxes and inclosures for heat radiators that shall simplify the work and reduce the cost to the minimum in their application to the radiators. Another object is to providean improved ventilator wall-box and also an improved air-duct for connecting the base box of the radiator with the wall-box in order to obviate the necessity for cutting and fitting different parts when making the connections between the base box and the wallbox. A further object is to provide an improved base box and radiator inclosure that may beset up in proper place without it being necessary to lift and carry the radiator and place it onto the base box, an object being to provide a convenient indicator for the ventilator apparatus, and a more specific object is to provide an improved sectional ventilator structure that shall be adjustable to the size of the radiator, in order to avoid the labor and expense incidental to handfitting when installing or repairing the ventilating or the heating appliances.

With the above-mentioned and other objects in view the invention consists in a sectional ventilator base box of improved construction for connection with a radiator and provided with an improved intake duct, an improved sectional wall box with which the duct is adjustably connected, an improved radiator inclosure adapted to be readily connected with the base box so as to inclose a portion of the radiator, and

Similar reference characters on the different figures of the drawings indicate corresponding elements or features of construction herein referred to,

In the drawings the numeral 1 indicates the wall of a building and 2 the floor of a room or apartment, the wall having an aperture 3 therein adjacent to the floor, being in many cases below a window at which a radiator is appropriately placed on the floor. The radiator comprises a suitable number of sections 1 connected together, the opposite sides of each section having joint bosses 5 and 5 respectively, as will be understood, and the end or terminal sections of the radiator are provided with supporting legs 6 and 7 respectively that rest upon the floor. The complete radiator, as will be understood, is very heavy, being composed of cast metal.

The improved well box is composed of cast metal so as to be durable and is inserted in the aperture 3, and it comprises a bottom plate having a flat inner portion 8 and an inclinedport-ion '9 that slants downward torverd the front of the Well and hes a downweirdly extending outer flange 10 and an upwardly extending inner flange 11 thereon; and a. top plate comprising afiet inner portion 1:? and an inclined outer portion 13 eX- tendimg upward toward the outer face of the well and'horing an upwardly extending outer flange 14 and a downwardly extending ilenge 1.5; said plates being connected to snitihle end walls. bottom and top plates are or" proper le tli conform to the preeirinngzed plans, n some cases being longer or shorter than in other cases. The f of the port 1 plate are ded 1 lth projec n rs 16 and 17. An end wall plate 18 is provided which is (1,. .ed between the he .11 and top plates or one end thereof and it hes an outwardly ing flange 19 an inwardly e1- tendiref flange 20, the nicer side of the Wall ts saving a suitable number of inclined s 21 thereon bellies t e dongs Anend Wall. plate 22 is 'ilcced between the cm and top pistes the opposite end eoi end it has on ontrvzirdly extending :nge and an inwardly extending flange so, the inne side of the end wall plots hav- 55 er eon behind the The end wens have. each a pair of ontiverdly extending cars 26 and 9.? thereon that have contest the adj scent ears or the bottom end top plates and are comrscted thereto by means of suitable derices and 28", such as bolts or rivets. The end Walls are or" suitable height to conform to the prearranged plans, in some cases being greater or less in height than others. It thus be seen that by selecting hottoni and top plates and end walls from the stock on hand a well box of the required dimensions may be readily built up, and in case of occidental fracture of one or the sections of the well box it may read- I ily be replaced by a new section Without discarding and losing a whole Well hon. The outer flanges of the difierent parts or sections of the Wall box, being joined together, form a complete external flange that is placed againstthe outer face of the building wall and closes the apertme 3. A suitable number of deflectors 29 are placed upon the ledges 21 and behind a screen 30 which is placed behind a continuous inner flange formed by the inner flanges of the different sections of the box.

The base box is also composed of cast metal sections or parts so that it may be able dimensions selected from stool: parts, in some cases the box being longer or shorter than in others. a back wall plate 31 having a large aperture 32 therein, the outer side of the plate having a. flange 33 thereon that extends around the aperture, the normal inner side of the plate having ears 3%, 35, 36, 37 thereon, there being two cars at a short distance from each end of the plate. An air-duct is composed of sheet metal and comprises a bottom 38, s. top 39, and end walls 4:0 and 4-1 connected to the bottom and the top, one open end of the air-duct being inserted in end soured to the flange 33 by means of bolts 4:2 or similar devices. The opposite open end of the air-duct is adapted to be inserted edjustablv into the wall box so as to practically become an extensible portion thereof, and, to this end the bottom 38 has Wzirdly extending resilient lip l3, 5 having a similar lip :14, the end We.

are sprung into contact- With the portions of the Wall box. The rear plate of the base box thus may he 1 located more or less closel}, to the position of the radiator. The upper portn or the opposite ends of the wall plate. 31 preferably are recessed to form upv-vird facinp; shoulders i? and 428 on opposite ends respectively of the plate.

Each of the opposite ends of the hose he is composed of two sections, the end walls thus comprising two rear sections -33- end 50 that are placed on the outer side of the ears that are on the respective end portions or the rear Wall plate 31 and secured to the ears by means of bolts 51 and 51'", the sec.- tions extending forward from the well i We The upper portions of the end sections are recessed so as to form upward facing shoulders 5:2 and 53 on the exterior of the respective sections and on the plane of the shoulders 4'? and 48 respectively. The forward portions of the sections have concave recesses 54 and 55 in the upper portions thereof respectively to receive the rearward portions of the bosses 5 and 5, respectively, of different sections of the radiator behind which the rear wall plate 31 extends, each end wall section extending between two of the radiotor sections. The end wall sections have also external ears 56 and 57 thereon below the recesses, respectively. The base box comprises also a front wall plate 58 that has cars 59, 60, 61, 62 on its inner side, there being two cars at a short distance from each end of the plate. The upper portion of the plate is recessed so as to form an upward facing shoulder 63 on its front portion. The remaining end Wall sections 6% and 65 are placed against the outer sides of the cars that are on the respective ends of the front The base box comprises plate 58 and secured to the ears by means of bolts 66 and 66, the forward end sections being placed in contact with the rear end sections and being recessed have upward facing shoal filers 67 and 68 on the outer side of their upper portions that are on the plane of the shoulders of the rear end sections and the forward wall plate. The forward end sections are placed between sections of the radiator and have concave recesses 69 and 70 in the upper rearward portions thereof that receive the forward portions of the bosses of the radiatorsections, the two concave recesses of the adjacent end sections forming a circular aperture that receives one boss. The forward end sections have also ears 71 and 72 on the exterior thereof below the concave recesses that are secured to the ears 56 and 57 respectively by means of bolts 73, 73. The base box, as will be seen, rests upon the floor 2 and extends upward to a plane above the joint bosses of the radiator so as to inclose the lower portions of the desired number of radiator sections.

A radiator-inclosure or casing is provided which preferably is composed of galvanized sheet metal and comprises a back wall 74 that is placed behind the radiator and has a recess 7 5 in its lower portion to receive the flange 33, the back wall having downwardlv 7 extending end portions 76 and 77 that extend to the plane of the shoulders 47 and 48 of the rear wall plate 31, the wall 74 being secured to the upward projecting portion of the rear wall 31 by means of bolts 78. The rear wall has rearwardly extending flanges 7 9 and 80 on the opposite end portions thereof respectively. The inclosure comprises also a front wall 81 and end walls 82 and 83 connected thereto, and extending past the plane of the wall 74 to the outer sides of the flanges 7 9 and 80m which they are secured by means of bolts 84 and 85, respectively. The front wall 81 is seated on the shoulder 63 and secured to the upper portion of the front wall plate 58 by means of bolts 86, the,

walls 82 and 83 seated uplon the shoulders 52 and 53 and secured to t e upper portions of the end walls by means of bolts 86, it being understood that the end walls 82 and 83 are readily inserted between the adjacent sections of the radiator above the lower oint bosses thereof. The inclosure extends upward to a suitable height so as to form a flue to conduct the fresh air upward about the radiator sections.

In order to re-heat the cooler air in the room, the front wall plate 58 of the base box has a-doorway 87 therein to be closed by a front damper 88 which is mounted on hinges 89 and 89 on the inner side of the wall plate adjacent to the bottom of the doorway, the rear side of the damper having a link 90 pivotally connected thereto. The inner side of the back wall plate 31 is provided with hinges 91 and 91 adjacent to the bottom of the aperture 32, the hinges supporting a back damper 92 to operate in the inta (e air-duct for regulating the admission of fresh air, the damper extending upward against stops 93 formed at the top of the aperture 32, so that the damper may entirely close the air-duct. The forward side of the damper has an ear 94 thereon to which a link 95 is pivoted. A fulcrum-arm 96 is secured to the inner side of the rear wall plate 31 below the aperture 32, and'a lever 97 is pivotally support-ed between its ends on the fulcrum arm, the opposite ends of the lever being pivotally connected to the links 90 and 95 respectively, so that when the front damper, which is provided with an operating knob 98, is closed the back damper is opened, the latter being moved to closed position when the front damper is opened, or is partially closed when the front damper is partially opened.

In some, cases the front and back of the radiator inclosure are 99 and 100 that extend to the radiator to centrally guide the inclosure.

In order that the position of the back 'damper 92 may be indicated to those interested, and who may not be familiar with the whereby to apply a connecting rod to the ear. The front of the plate has a 'si n 106, such as Shut, and another sign 1O such as Open, thereon, either sign to be brought by movement of the plate to the sight-opening. Preferably the indicator plate is arranged in a uide 108 secured to the inner side of the front 81. The plate 102 may be variously operated and controlled; preferably by means of a wrist pin 109 fixed on one end of the front damper 88, and a connecting rod 110 having an eye 111 that is connected to the 'pin, the rod being composed of spring-wire so as to be slightly. flexible laterally, as it extends through a guide 112 secured to the inner side of the front 81. The rod 110 is suitably connected to the ear 104, preferably adjustably by means of a clamp bolt 113 in serted in the ear 104 and a nut 114 on the bolt at one side of the ear, the bolt having a hole 115 therein to receive the rod 110 for clamping the rod to theopposite side of the ear.

provided with guides It will be seen from the foregoing that after installing the ventilating appliances, if for any reason it be found desirable to increase or decrease the base box and inclosure capacity the same may be readily accomplished by disconnecting the parts of the same and supplying corresponding parts of different dimensions without disturbing the radiator.

In practical use the simple adjustment of the front damper 88 effects the control of the back damper 92, so that the admission of air into the room is readily controlled. When the front damper is closed, as in Fig. 1, the back damper extends fiatwise upon the bottom of the air-duct, so that the full capacity of the latter is available for the admission of fresh air, and when less is desired the-air-duct is partially closed automatically on partially opening the front damper or may be entirely closed so as to re-heat the air in the room upon full opening of the front damper. The air rises in the inclosure or flue and becomes heated by the radiator in its passage to the top of the inclosure, the walls of the inclosurebecoming heated by the heated air so as to radiate heat. When the front damper is closed and the back damper open the open sign 107 appears at the sight-opening 101; and when the back damper is closed by the front damper when lowered to .open position, the latter pulls down the rod 110 and swings the plate 102 down so that the shut sign 106 appears at the sight-opening.
